UNDERGROUND STORAGE TANK SURVEY

Recently a consulting company asked to employ our services at a site in Pomona to conduct a geophysical evaluation for the existence of underground storage tanks. Historically, the property was occupied by a number of manufacturing facilities and a gasoline service station. It is our understanding that several USTs had once existed on site, however, records indicating the location of these USTs are unclear.

Subsequent to conducting an **EM61 survey, GPR traverses were conducted over all EM anomalies found. A cylindrical object (possible UST) was found associated with one of the large EM anomalies.
